Çeşme is a Turkish resort town west of Izmir, on the Aegean Sea. Overlooking the harbor is Çeşme Castle, a restored military fortress. It now houses the Çeşme Archaeology Museum, with displays of marble busts, metal coins and artifacts from nearby excavations. On the east side of the Çeşme peninsula is sandy Ilica Beach, with warm thermal sulfur springs. Around Çeşme are clear waters and accessible dive sites.
